Y06: Neglect and abandonment

Y06.9: By unspecified person

ICD-10 code Y06.9, titled "By unspecified person," refers to incidents of physical, psychological, or sexual maltreatment inflicted by an unknown or unspecified person. This does not refer to a medical condition but rather is part of a comprehensive system that categorizes and codes varying incidents of abuse or harmful behaviors. Abuse, in this context, can present in many forms such as injury, emotional trauma, or sexual violence. Symptoms can vary widely depending on the nature of the incident and could include physical injuries, emotional distress, anxiety, depression, or psychosomatic symptoms. This diagnostic code is used when the perpetrator of the abuse hasn't been identified or specified in a clinical setting.
